8、n The Directory: Models Technical Corrigendum 2 Source Corrigendum 2 to ITU-T Recommendation X.501 (2005) was approved on 13 November 2008 by ITU-T Study Group 17 (2009-2012) under ITU-T Recommendation A.8 procedure. An identical text is also published as Technical Corrigendum 2 to ISO/IEC 9594-2. i
9、i ITU-T Rec. X.501 (2005)/Cor.2 (11/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent o
10、rgan of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes th
11、e topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards ar
12、e prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendat
13、ion may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used
14、to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectu
15、al Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received no
16、tice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU

Change attributeIntegrityInfo to: attributeIntegrityInfo ATTRIBUT
19、E := WITH SYNTAX AttributeIntegrityInfo SINGLE VALUE TRUE ID id-at-attributeIntegrityInfo c) After the current ASN.1, add: integrityInfo OBJECT-CLASS := SUBCLASS OF top KIND auxiliary MUST CONTAIN attributeIntegrityInfo ID id-oc-integrityInfo d) After NOTE 1 in 20.2, add: The creator of the attribut
20、eIntegrityInfo attribute shall, when creating the AttribsHash data type, use DER encoding (see 6.1 of ITU-T Rec. X.509 | ISO/IEC 9594-8) of the attributes ordering the attributes as specified above, and then create the hash from the resulting encoding. NOTE 2 The creator needs to have full knowledge
21、 of all the attribute syntaxes to create the hash. The verifier of the integrity shall produce its own version of AttribsHash using the same procedure as above for retrieved attributes, and then compare the result with the value in the attribsHash component. NOTE 3 The verification is only possible
22、if the verifier has full knowledge of all the attribute syntaxes. An entry that shall hold an attributeIntegrityInfo attribute shall include the integrityInfo auxiliary object-class.
